This hall ticket of Calcutta University is in all probability an oldest certificate as far as the education of Sikkim is concerned. Issued in 1932, the document has given detail information about the subjects that were taught at Calcutta University during the colonial era. The important feature of this hall ticket is that it is hand written. In that period, there were very few schools in Sikkim and most of them were providing education only up to the primary level. The first Government school of Gangtok was Gangtok School which was started in 1906, and this is where the late Maharaja of Sikkim, Sir Tashi Namgyal also studied as a first batch student. Later, the name of the Gangtok School was changed as Gangtok High School.

Before 1920, there were two Boarding Schools at Gangtok: The Bhutia Boarding School and The Nepali Boarding School. It was due to the diligent endeavor of late Rashmi Prasad Alley both the Schools were united which later played a vital role for the foundation of first ever high school at Gangtok. The Gangtok High School was later named after the name of its first batch student and the then Maharaja of Sikkim Sir Tashi Namgyal. Though, with the efforts made by Lt. Rashmi Prasad AlleyGangtok got its first ever High school but, it was not an easy task for him to run it successfully. Due to the lack of higher institution in the proximity of the Kingdom, the only High School of Sikkim (Gangtok High School) was then affiliated to the Calcutta University.
